What Is a Credit Card?

A credit card is a financial tool that allows a borrower to make purchases using a plastic or metal card. While a debit card uses money from the borrower’s checking account, a traditional credit card borrows from a predetermined credit limit. The average American has three credit cards in their name.1

These are a few different types of cards available: 

  • Rewards credit card 
  • Student credit card 
  • Travel credit card
  • Business credit card 
  • Secured credit card 

Credit card companies issue credit cards based on specific financial requirements. When someone submits an application, the financial institution does a credit check to determine approval, the interest rate, and the maximum limit.  

Responsible Credit Card Usage 

A borrower uses a credit card just like a debit card. The card can be swiped, tapped, or inserted into a payment terminal, or used online to purchase goods and services. The borrower is expected to repay the card monthly. However, the borrower has various options for repayment. 

Cardholders can pay the minimum amount required by the bank, or as much as they desire. But while it’s convenient to only pay the minimum, financial experts advise borrowers to pay the full statement balance (amount shown on the monthly billing statement) so the debt does not grow into an unmanageable amount. 

Here are 5 tips to ensure you use a traditional credit card responsibly:

  1. Don’t use more than you can afford to repay.
  2. Never skip or forget to make a payment.
  3. Pay more than the minimum each month. 
  4. Avoid using more than 30% of your limit. 
  5. Use a rewards card instead of a standard credit card. 

Credit Card Financials

The interest rate on a credit card, often referred to as the Annual Percentage Rate (APR), varies depending on the card issuer, your creditworthiness, and the type of credit card you have. 

The average credit card interest rate is 21%.2 However, some cards offer lower introductory rates for a certain period, while others have higher rates for cash advances. As for fees, credit cards may come with various charges, such as:

  • Annual fees
  • Cash advance fees
  • Balance transfer fees
  • Foreign transaction fees
  • Late payment fees

It’s crucial to read your card’s terms and conditions to fully understand all potential charges. Based on 2022 data from the Federal Reserve and the U.S. Census Bureau, the average American has $7,951 in credit card debt.3 There is no right amount of outstanding debt to have. The most important factor is that you can comfortably repay your debt and other necessary expenses.

Age Requirements for Credit Cards

You may ask, “How old do you have to be to get a credit card?” According to modern law, borrowers must be at least 18 years of age in order to get a credit card account. 

It is actually illegal for credit card companies and other lenders to approve loans or lines of credit for individuals who are under the age of 18. However, there are still some ways younger adults can start using lines of credit. 

How To Get a Credit Card if You Are Under 18

How can you use a credit card if you are under the age of 18? While you can’t have your own credit card if you are underage, you may be able to use one under the account of another established borrower. 

  • Become an Authorized User — Authorized users have access to a credit line linked to another primary cardholder’s account. Authorized users can make purchases but the primary account holder is responsible for paying the balance on the authorized user’s behalf. 
  • Get a Secured Credit Card — Some lenders allow minors to have secured credit cards. A secured card differs from an unsecured card in that the credit limit is prepaid. Since the credit limit for secured cards is paid upfront, there is very little risk of accumulating too much credit card debt.

What Are the Requirements To Get a Credit Card?

The basic requirements for most credit card issuers are: 

  • Applicants must be 18 years of age or older. 
  • Applicants must have reliable independent income. 
  • Applicants must provide an SSN or ITIN. 

If an applicant meets those basic requirements, chances are they will be able to find approval from some sort of credit card. Lenders will also do a hard credit check to determine approval, interest rates, and other funding details. 

How Does Your Credit Score Affect Approval for a Credit Card Account?

There are five main categories credit bureaus collect data on to compile your credit score and determine your credit score. 

Payment History

Payment history includes paying bills and other financial obligations on time, like credit card balances. How on time you are with making payments is the most influential factor that goes into your credit report. Missing just one monthly payment on your credit card can negatively affect your credit score for up to seven years! 

Credit Mix

Credit bureaus also look at what kind of financial accounts you have. Generally, a mix of accounts is preferable. For example, having lines of credit, installment loans, payday loans, secured loans, etc. A credit mix shows that you are capable of responsibly managing your debt. 

Length of Credit History

One of the financial factors that contribute to credit scores is the length of financial history. The longer you’ve had an open financial account in your name, the more your credit score will benefit. 

Debts Owed

How much good debt vs bad debt you owe also contributes to your credit score. This means if you have a large outstanding balance on your credit card, you may see your credit score suffer because of it. 

Hard Credit Checks 

Every time you apply for loans or credit cards, lenders perform a hard credit check. Hard credit checks are a formal inquiry into your credit profile and are kept track of by credit bureaus. So, if you apply for too many lines of credit you aren’t qualified for, you may find that applying for credit cards hurts your credit

How To Establish Credit History if You Are Under 18 

The sooner you can start establishing a credit history, the better. Below are a few tips on how minors can start generating their credit history as quickly as possible. 

Secured Cards / Authorized Users 

As discussed, having a secured card or being an authorized user allows young adults access to credit cards. Additionally, when used responsibly, these financial products can help young adults build credit and start establishing a healthy financial history.

Get a Checking Account & Savings Account 

It is also a good idea to open a bank account for a young adult as soon as possible. While a minor may not have their own checking account, they may have what is called a custodial account. A custodial account essentially functions exactly like a regular bank account, except a custodial account is under the control of someone over the age of 18 on behalf of a minor. 

FAQs About Getting and Using Credit Cards

What are some practical tips for managing my credit card?

Set a realistic budget and stick to it, keeping your credit utilization low. Set up automatic payments to avoid late fees, and review your monthly statements for accuracy. Don’t hesitate to contact your issuer if you have questions.

What are the benefits of having a secured card?

Secured credit cards can help build or repair credit scores, as they require a deposit that secures your line of credit. They’re a great option if you’re new to credit or are looking to improve your score.

Are there any drawbacks to using student credit cards?

While student credit cards are a fantastic way to start building credit, they often come with higher interest rates and lower credit limits. Also, inexperienced users might find it tempting to spend beyond their means.

How do interest rates affect my credit card balance?

Interest rates are the cost of borrowing money. If you don’t pay off your full balance each month, you’ll be charged interest on the remaining amount. This interest compounds, so over time, you could end up owing much more than you originally spent.

How do I choose the right credit card for my needs?

Consider your lifestyle and spending habits. If you’re a student, student credit cards might be beneficial. If you’re working on building credit, secured credit cards could be a better fit. Always compare interest rates, rewards, and fees.

Can I use someone else’s credit card account?

Yes, but only if you’re an authorized user. Being an authorized user means the primary account holder has explicitly given you permission to use their card. While the authorized user can make charges, the primary cardholder is ultimately responsible for the balance.

What should I do if I can’t pay my credit card bill?

Don’t panic! Contact your credit card issuer immediately. Most credit card issuers will work with you to find a solution, which may include a payment plan or temporary hardship program.

Who should I contact if I have questions or concerns about my credit card?

For any questions or concerns, reach out to your credit card issuer’s customer service department. They can assist with billing inquiries, payment options, and other account-related questions.
